1. 使用Nginx代理ws

server {
    listen 8086; # 监听8086端口
    server_name   192.168.1.123;  #也可以是域名
    add_header Access-Control-Allow-Origin *;
    location / {
        #添加wensocket代理的目标服务器
        proxy_pass http://192.168.1.3:8888;  
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_connect_timeout 1800s;
        proxy_send_timeout 1800s;
        proxy_read_timeout 1800s;
    }
}

2.使用Nginx代理wss

说明：如果是内网环境使用，可以手动创建证书使用，如果是公网环境，则必须为公网域名证书或ip证书，使用域名可以去阿里创建免费证书并下载就可以了。

server {
    listen 9006 ssl; # 监听9006 端口
    server_name    自己的域名.com ;
    ssl_certificate       /etc/nginx/xxx.com.pem;
    ssl_certificate_key /etc/nginx/xxx.com.key;
    ssl_session_timeout 5m;
    ssl_session_cache shared:SSL:10m;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2 SSLv2 SSLv3;
    ssl_ciphers ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP;
    ssl_prefer_server_ciphers on;
    ssl_verify_client off;
    add_header Access-Control-Allow-Origin *;
    location / {
        #添加wensocket代理
        proxy_pass http://192.168.1.3:8888;  # websocket服务器。不用管 ws://
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_connect_timeout 1800s;
        proxy_send_timeout 1800s;
        proxy_read_timeout 1800s;
    }
}
